Trying something new where on Sundays, I’ll share what I’m reading, watching, cooking, and up to this week over on Substack. Read it here: https://open.substack.com/pub/drteplinsky/p/sunday-notes?r=645vr&utm_medium=ios

A true honor yesterday to moderate the breast cancer survivorship panel at the 2026 Let’s Talk Women’s Health and Wellness with these incredible panelists and women:
and .

We talked about so much but I wanted to share some central themes (these apply to people living with metastatic cancer as well).

1. Survivorship is quieter and it’s hard (sometimes harder than active treatment). Find your community of people who get it.

2. Address your mental health (often so stigmatized).

3. Think about staying in the moment and moving forward rather than trying to look back.

Let me know your thoughts and experiences.

Another day, another sensational media headline. Let’s break down this study in detail: it looks at the impact of complementary and alternative medicines in breast cancer — they have a negative impact on breast cancer outcomes (but so does not doing any treatment).

I break down this study in this video and also on my most recent substack — https://open.substack.com/pub/drteplinsky/p/breast-cancer-complementary-and-alternative?r=645vr&utm_medium=ios

Let me know your questions!

Some 📍LA highlights from this past weekend to visit (if you need a photographer in LA, I’m biased but she is amazing 😉) and run the ! A super hot 🥵 but fantastic race and absolutely incredible crowd support!

I started running in high school and started running half marathons and marathons in 2012/2013. I love the mental and physical challenge of long distance running and it’s something that I get to do completely for myself. (Bonus is when I can run a race while fundraising for a charity to raise funds for cancer research).

Already planning for the next ! London or Boston 2027? 🤷‍♀️ need to find a charity to run with!

What’s something you do for YOU that brings you joy?

Love that this year is on International Women’s Day and this message is empowered women empower women is one of my favorites - and why I am so passionate about education and advocacy.

A marathon is challenging on a good day but tomorrow is going to be especially tough with temperatures predicted to be in the mid 80s at the finish. A big change from the 14 degree ❄️ training runs this winter!
Hoping to go out there and have fun and enjoy the LA sights!

New Substack on alternative treatments and misinformation in cancer and a new study making headlines about complementary and alternative therapies and breast cancer outcomes. The 📰headlines are a bit sensational and click-bait so I break down what the actual study tells us.

March 3rd is Triple Negative Breast Cancer Day and I can’t think of a better day to tell you about a new study just published in Nature of a first in human phase 1 trial of a personalized mRNA neoantigen TNBC vaccine.

The patient population was 14 individuals with surgically removed, early-stage triple-negative breast cancer. For each participant, researchers created a personalized mRNA vaccine encoding up to 20 neoantigens. Neoantigens are proteins that forms on cancer cells when certain mutations occur in tumor DNA. The goal was to train the immune system to recognize these neoantigens as foreign and attack tumor cells that carry these neoantigens. The goal is to reduce risk of recurrence and/or eliminate microscopic disease.

What they found was that the vaccine was well tolerated and either expanded pre-existing or induced immune-cell responses against at least one vaccinated neoantigen in all 14 evaluable individuals. Eleven patients remained relapse-free for up to six years post-vaccination (!!).

This is very early but promising and encouraging data! Multiple TNBC vaccines are in development (can search on clinicaltrials.gov) and I’m hopeful for the future!

Let me know all your questions!

Amy is also the bestselling author of “Baring it All: Reflections of My Breast Cancer F*ckery”, and a dynamic speaker who lights up a room and emanates vibrant energy.

On today’s episode, we talk about taking care of your mental health, starting to feel at home in your body again, trusting yourself and finding community and connection. Amy is hosting the upcoming RISING Retreat, an intimate retreat for breast cancer survivors and women living with metastatic disease to rest, reconnect with their bodies, and unapologetically claim who they are. Amy also shared a beautiful meditation she recorded to help women regain trust in themselves and in their bodies after breast cancer.

You can find this episode of the Interlude Podcast anywhere you listen to podcasts or on my website, www.drteplinsky.com. Comment PODCAST and I’ll send you the link to the episode and to the meditation!

I went for my mammogram a few weeks ago. I have dense breasts so I also had an ultrasound done! 🙌 all was negative. Mammograms save lives and help us diagnose breast cancer at its earliest point!!

3 key facts to know about breast cancer screening:

1️⃣ Know your breast cancer risk. Screening for average risk individuals starts at 40 but earlier for higher risk individuals. There are many models available to calculate your breast cancer risk including the Tyrer Cuzick model.

2️⃣ If you have dense breasts, consider adding in supplemental screening w MRI or breast ultrasound.

3️⃣ If you are at higher than average risk, you might benefit from supplemental imaging with ultrasound or MRI.

Are you up to date with breast cancer screening?! Let me know your questions!

Answering your questions on ovarian suppression in breast cancer:

1) Do you still get a period?
2) Does switching from Lupron to Zoladex or vice versa help with side effects?
3) Oophorectomy (removal of ovaries) vs ovarian suppression w Lupron or Zoladex?

Hope this helps and let me know other questions you have!

Let’s talk about circulating tumor DNA. If there are cancer cells in the body, as they die, a small amount of cancer cell DNA is released into blood circulation. We can sequence the primary tumor to identify the mutations present in the cancer, and then test for those mutations in the blood. Detection of circulating tumor DNA (ctDNA) in blood, after treatment for primary breast cancer, is associated with a higher risk of future recurrence. Signatera is one test available to look for ctDNA but there are many others (through companies like Caris and Guardant as well). ***we can’t always detect ctDNA especially in early stage cancer and there are limitations to the technology as well.

There is some nuance with this test and we often don’t know what to do if the results come back positive but staging scans are negative. Fortunately, there are many ongoing exciting clinical trials with ctDNA in breast cancer looking at interventions so hopefully we will have more answers soon! Currently on clinical trials.gov, there are about 100 breast cancer ctDNA trials! I want to highlight three that I think are important (but there are others!):

1. Decreasing Treatment for Metastatic HER2-Positive Breast Cancer With Undectable Cancer Levels in Blood Tests. (HEROES)

2. DNA-guided Second Line Adjuvant Therapy for High Residual Risk, Estrogen Receptor Positive, HER-2 Negative Breast Cancer (DARE) (DARE)

3. Atezolizumab + Sacituzumab Govitecan to Prevent Recurrence in TNBC (ASPRIA)
